Use your elbows or forearms for things like turning on the water or pushing the door open. And if it's something you HAVE TO touch, like the door handle when you leave, you use a paper towel over your hand and toss it in the trash on the way out.
I would never flush with my bare hand or even with some tp. Because if it's wet (most likely with urine), that will seep right through that tp. Nothing is going to seep through my shoe!
And yes I realize you can just wash your hands after but I'd rather avoid having a stranger's urine on my hand to begin with.
So how bout you? How do you flush in public restrooms? Bare hand? Tp? Foot? Something else?
Oh, also, I hover and squat and never put my butt on the seat lol.
